Question
Arrange the following in the order of property indicated for each set:
F2, Cl2, Br2, I2 – increasing bond ethalpy.
Solution
The bond dissocation energy decrease down the group. As size increase.In the order of increasing bond energy Cl—Cl bond energy is highest while I—I bond energy is least.
I-I < F-F < Br-Br < Cl-Cl
I-I < F-F < Br-Br < Cl-Cl
